GUI toolkit

[lewark]

From the LV2 github wiki:

https://github.com/x42/robtk - Robin's LV2 UI ToolKit. x42. Robin doesn't recommend using.

So far, robtk has worked fine, but if this is true I still might want to consider AVTK, BWidgets, Redkite, or another toolkit that is designed for use by third-party plugins.

One thing robtk has over AVTK and Redkite is cross-platform support (see #7). The README on the BWidgets repo states that it should work on other platforms as well, however both it and Redkite use GPLv3 while rt_lpc uses the incompatible GPLv2. So by the looks of it robtk and AVTK are the only options out of the ones I listed, and robtk is the one that is still actively maintained. I think it is best to stick with robtk for now, though there are still many other toolkits based on PUGL that might be worth looking into.
